Definitions
- the present invention relates to a hurley stick, and to a method for manufacturing a hurley stick.
- a hurley stick is a ball striking club, which is used in a game of hurling.
- a hurley stick comprises an elongated shaft which defines a longitudinally extending shaft axis and terminates in a ball striking boss.
- a hurley stick for an adult in general, is of overall length from a proximal end of the hurley stick to the distal end thereof in the order of 800 to 900mm.
- the hurley stick is used for striking a ball, normally referred to as a sliotar, in the game of hurling which is of a substantially similar size to that of a conventional tennis ball.
- Hurling is a traditional Irish game which is played by two teams of players opposing each other, each team comprising fifteen players including a goalkeeper.
- Each player including the goalkeeper is provided with a hurley stick, which is used for striking the ball (sliotar) for passing the ball from one player to another and for scoring a goal or a point.
- a goal is scored by striking the ball past the goalkeeper into a net which is supported between a pair of upstanding goalposts and an upper crossbar extending between the goalposts.
- a point is scored by striking the ball over the upper crossbar between the upstanding goalposts.
- Hurley sticks traditionally have been made from ash wood with the ash wood oriented so that the grain of the ash wood extends substantially parallel with the shaft of the hurley stick, and curves around into the ball striking boss.
- Ash wood is chosen because of the grain structure of ash wood, and in particular, the resilience of ash wood.
- hurley sticks are formed from a lower portion of the trunk of an ash tree and a part of the root of the ash tree adjacent the lower end of the trunk thereof. Due to the grain structure of the ash tree between the lower portion of the trunk and the root, the grain of the trunk curves outwardly towards the lower end of the trunk and into the root.
- the hurley stick is formed from the lower portion of the trunk and the adjacent portion of the root, so that the grain of the ash wood extends longitudinally along the shaft and curves into the boss.
- This construction of a hurley stick provides a robust hurley stick which can withstand significant ball striking forces.
- the resilience of ash wood is such that the shaft and indeed the boss is capable of absorbing significant impacts and ball striking forces without any damage to the shaft or the boss of the hurley stick.
- a problem has arisen in that the availability of suitable ash trees at reasonable cost for the production of hurley sticks is insufficient to meet the current demand.
- An additional and a more important problem relates to the modern ball and the relatively oversize boss of modern hurley sticks.

- the elongated members of the at least one of the lamina of the piece of the laminated material are arranged side by side to define the lamina.
- each elongated member of the at least one of the lamina of the piece of the laminated material is of one of square transverse cross- section and rectangular transverse cross-section.
- the elongated members of rectangular transverse cross-section of the at least one of the lamina of the piece of the laminated material define respective opposite spaced apart major surfaces joined by respective opposite spaced apart minor surfaces, the major surfaces of the elongated members of the lamina defining respective opposite major surfaces of the lamina.
- the elongated members of rectangular transverse cross-section of the at least one of the lamina of the piece of the laminated material are joined together along their respective minor surfaces.
- the elongated members of the at least one lamina of the piece of the laminated material are bonded together by an adhesive.

- the hurley stick 1 comprises an elongated shaft 2 extending from a proximal end 4 to a distal end 5 and defining a shaft axis 6 extending longitudinally along the shaft 2, and terminating at its distal end 5 in a ball striking boss 7.
- the shaft 2 defines an upper handle portion 8 which terminates adjacent the proximal end 4 in a stop end 9 formed by a rearwardly projecting portion 10.
- the shape of a hurley stick will be well known to those skilled in the art, and it is not intended to describe the hurley stick itself in further detail.
- the shaft 2 has good resilient bendable characteristics along the shaft axis 6 from the proximal end 4 to the distal end 5 of the shaft 2, and in particular, between the upper handle portion 8 of the shaft 2 and the boss 7 in order to absorb the impact of a strike of a ball by the boss 7 without fracturing of the shaft 2 or the boss 7.
- the hurley stick 1 is formed from a blank 11 , which is cut from a single piece 12 of laminated material in the form of a sheet.
- the piece 12 of the laminated material comprises at least two lamina 14, and in this embodiment of the invention three lamina 14, namely, a pair of outer lamina 14a which substantially form outer major surfaces 15 of the hurley stick 1 , and a central lamina 14b sandwiched between the two outer lamina 14a.
- the lamina 14 of the piece 12 of the laminated material are bonded together by a waterproof adhesive.
- the lamina 14 are manufactured from a fibrous material, which in this embodiment of the invention is derived from a bamboo material.
- Each lamina 14 comprises a plurality of elongated members 17 of substantially square transverse cross-section formed from the fibrous bamboo material, with the fibres of the bamboo material oriented in a general longitudinal direction parallel to the corresponding elongated member 17.
- the members 17 are arranged side by side extending parallel to each other in each lamina 14, and adjacent ones of the members 17 of each lamina 14 are bonded together by a waterproof adhesive to form the corresponding lamina 14.
- each lamina 14 Due to the construction of the lamina 14 each from a plurality of the elongated members 17 of the bamboo material, each lamina 14 has a resilient bending characteristic along a first axis 19 which extends parallel to the elongated members 17 which is superior to a resilient bending characteristic of that lamina 14 along a second axis 20 extending transversely of the first axis 19.
- the first axes 19 of the two outer lamina 14a of the piece 12 of the laminated material extend parallel to each other, while the central lamina 14b of the piece 12 of the laminated material is oriented relative to the two outer lamina 14a with the first axis 19 of the central lamina 14b extending transversely, in other words, at approximately 90° relative to the first axes 9 of the two outer lamina 14a.

- the hurley stick 1 is provided with a resilient bending characteristic along the shaft axis 6 which is superior to the resilient bending characteristic of the shaft 2 transversely across the shaft 2.
- the hurley stick 1 is also provided with a reasonably good resilient bending characteristic transversely across the shaft 2, and in particular, transversely across the boss 7 to avoid any danger of a forward portion 22 of the boss 7 fracturing from the remainder of the boss 7 in the event of a ball strike of the boss 7 adjacent the forward portion 22 thereof.
- the hurley stick 1 may or may not, as desired, be treated with a protective surface coating or with a protective oil, and the hurley stick 1 is ready for use.
- each lamina has been described as being formed from a blank cut from a single piece of laminated material which comprises three lamina, it will be readily apparent to those skilled in the art that the number of lamina may be greater than or less than three in the laminated material. Additionally, it will be appreciated that while each lamina has been described as being formed from a plurality of elongated members arranged side by side and extending parallel to each other, each lamina may be formed in any desired manner, and in certain cases may be formed by a single integral sheet of material.
- each lamina of the blank have been described as comprising fibrous material which has been derived from a bamboo material, any other suitable fibrous material may be used. Further, it will be appreciated that instead of the use of bamboo material, wood materials may be used, and in which case, the grain of the wood material would extend parallel to the first axis of the lamina. In cases where each lamina is formed from wood material, each lamina may be formed from a single integral sheet of the wood material, or a composite sheet constructed from a plurality of elongated members arranged side by side with adjacent members bonded to each other.
- first axes of the two outer lamina of the blank have been described as extending parallel to the shaft axis of the hurley stick, in certain cases, it is envisaged that the first axis of the central lamina of the blank may extend parallel to the shaft axis of the hurley stick, and the first axes of the outer lamina would extend transversely relative to the shaft axis of the hurley stick.
- the blank may be cut from the piece of the laminated material with the first axes 19 of the two outer lamina 14a extending at an angle greater than zero to the shaft axis 6 of the hurley stick, for example, at an angle of 45° to the shaft axis 6, and in which case the first axis 19 of the central lamina 14b would extend at a complementary angle to the shaft axis 6.
- the first axes of some of the lamina may extend at angles other than 90° to the first axes of other ones of the lamina of the laminated material.
- the lamina may be arranged relative to each other such that the first axis of one of the lamina extends at an angle less than 90°, and typically between 30° and 60° relative to the first axis of another or an adjacent lamina of the laminated material.
- the laminated material may comprise respective lamina of wood material and bamboo material.
- each alternate one of the lamina of the laminated material may be of wood material, while each other alternative one of the lamina of the laminated material may be of bamboo material.
- the wood material may be of a hardwood or a softwood.
- the elongated members from which lamina of the laminated material may be formed may be of transverse cross-section of shape other than square cross-section, for example, it is envisaged that the elongated members may be of rectangular transverse cross-section, and in which case, it is envisaged that each elongated member would define a pair of spaced apart opposite major surfaces, joined by a pair of spaced apart opposite minor surfaces, and typically, the minor surfaces of adjacent ones of the elongated members would be bonded together to form the corresponding lamina.
- the adjacent elongated members of rectangular transverse cross-section may be bonded together by their respective major surfaces to form a corresponding lamina.
- the elongated members have been described as being of bamboo material, it is envisaged that the elongated members may be of any suitable material, for example, wood material. It will also be appreciated that the lamina of the laminated material may be of different materials, for example, one lamina may be of bamboo material and another one or ones of the lamina may be of wood or other suitable fibrous material.
